Rendering quality question

[Gary Kleiner]

Theoretically, you would loose some quality compared to rendering the Mpeg from an earlier generation and/or original material. However, the difference may well be negligible in the real world.

Best way to tell is to do some test renders.

Import the .veg vegas project file you made into the new project (easiest is to drag and drop it), instead of importing the rendered file. Then when you render the new project the original project will be rendered from the source, and you’ll avoid second-generation losses. – Jong

Nested veg files first appeared in Vegas 6.

if you rendered out using the DV template ( 4:1:1) color space .. then bring that into Vegas to render a mpeg for DVD (4:2:2) color space = you lost 1/2 of the color info plus you have introduced stair stepping on all line edges that are not perfectly horizontal or vertical then if you rendered out of the TL (edited clips, photo’s text) to mpeg 2 …

if you need to make different files you could render out of Vegas using the dv template – custom – video then in format choose sony YUV ( 4:2:2 color space) codec .. then use that to render out to your mpegs, dv avi, wmv , QT etc …

Is this codec part of the Vegas 5 software package (can’t check now-I’m @ work) and what kind of quality loss will using this codec cause?
